Specification of Letters Patent.

Patented Nov. i3, 190e.

Application filed January 22, 1906. Serial No. 297,390.

To all whom, t may con/cern.:

Be it known that we, RALPH E. GIERHART and CHARLES O. HANSEN, citizens of the United States, residing at Argyle, in the county of Lafayette and State of Wisconsin, have invented certain new and useful Improvements in a Speed-Regulating Apparatus, of which the following is a specification.

This invention relates to improvements in an apparatus to be used for regulating the speed of various kinds of machines or a number of individual machines driven from the same shaft without affecting or changing the rate of speed of the engine or primary power; and it consists in certain peculiarities of the construction, novel arrangement, and o eration of the various arts thereof, as will be hereinafter more fu y set forth and specifically claimed.

The principal obj ect of our invention is to provide an ap aratus of the above-named character whlc .shall be Vsimple and inexpensive in construction, strong, durable, and effective in o eration, and so made that it may be emp oyed forthe regulation of the speed of machines when operated by 'any klnd of power, such as steam,'water, wind, hydrocarbon, or electricity.

In order to enable others skilled in the art to which our invention pertains to make and use the same, 'we will now proceed to describe it, referring to the accompanying drawings, in which` Figure 1 is a view in side elevation of a speed-regulating apparatus embodying our invention, showing the parts by continuous lines in their operative positions to transmit ahigh rate of speed from the main shaft to the individual machine or machine to be driven and by dotted ylines the positions the parts may assume in the operatlon of the device, and Fig. 2 is a sectional view taken on line 2 2 of Flg. 1 looking in the direction indicated by the arrows.

Like numerals of reference refer to corresponding arts throughout the different views of t e drawings, in which we have shown the apparatus in a vertical position; but we wish 1t understood that it may be placed horizontally or otherwise.

The reference-numeral 5 designates the main frame, which may be of any suitable size, form, and material, and has journaled thereon a main or driving shaft 6, which is usually mounted at one of its ends in a bearbeA driven. longitudinally movably, yet nonrotatably,-

ing 7 on a bracket 8, which extends laterally from the main frame near one of its ends, and in suitable bearings 9 and 10 on the other end of the main frame. Loosely mounted on the shaft 6 near one of its ends is a pulley 11, which receives power from an engine or other source of power-supply (not shown) throughl a belt 12 and is provided with a disk 13, which is preferably made integral therewith, as shown, so as to rotate with said pulley. Loosely mounted on the shaft 6, but non-rotatably secured thereto, is a pulley 14, which carries a disk 15 to coact` with the disk 13, las will be presently explained. Passing around the pulley 14 is a elt.16,'which extends to and engages a part of the individual machine or the-machine to V(N ot shown.) The pulley 14 `is secured on the shaft 6 by means of a rod or bar 17, which asses throu h a slot.18 in the shaft 6 and a so through tIie hub 19 of said pulley, as well as through a sleeve 20, which surrounds the shaft 6 and extends to near its u per end, as shown in the present drawings. Tlie upper end of the sleeve 20 is provided with an annular flange 21fand has lits portion just below said flan e reduced, thus forming an annular shou der 22, against which one end of 'a s r'ing 23, which surrounds the sleeve 20, w1 l rest. l

Loosely mounted on the reduced portion of the sleeve, just below the flange21 thereof, is

a collar 24, which has on one of its sides, a curved groove 25 to receive a portion of an eccentric 26, which is fulcrumed on the bracket 8 and has a handle 27, which is equipped near its free end with a grippinglever 28, which lever carries a pawl or catch 29 to engage the teeth of a segmental rack 30, secured to ythe main frame near the bracket 8 thereof. The sleeve 20 is provided between its ends and usually at or near the shoulder 22 with oppositely-disposed projections 31, to each of which is pivotally secured one end of a governor-arm 32, on the IOO otherend of each of which is mounted a ball or weight 33 of suitable size and material.-

ocated in a transverse opening 34 in the shaft 6 at a point near the projections 31 is a".

rod 35, which has its ends extended through longitudinal slots 36, formed in thesleeve 20 at a point-between the projections 31 and the pulley 14 thereon. Pivotall connected at one of their ends to each end7 of the rod 35 1ro are links 37, which are pivotally connected at' c through the belt 12 or a suitable connection 'will be decreased, thus to the pulley 11 the latter, as well as the disk 13,which it carries,will be caused to rotate on the shaft 6 until by reason of the frictioned contact therewith of the disk 15, carried by the pulley 14, said shaft, as well as the last-named pulley, will be caused to rotate, thereby transmitting, through the belt or connection 16, power to the machine to be driven. In this operation as soon as the velocity of the driving-shaft and the ulleys and disks thereon becomes sufficient, by reason of the centrifugal action of governorballs and arms, to overcome the pressure of the spring 23, which actuates the sleeve 20, it is obvious that the said sleeve will be moved on the shaft 6, so as to disconnect the disks 13 and 15, when by reason of the retarding effect of the machine being driventhe speed of the driving-shaft and sleeve 2O permitting the governor to again move the disk 15 into frictioned contact with the other disk. It is apparent that the tension of the spring 23 may e regulated to the desired degree by turning and securing the eccentric 26 in the proper direction, in which operation the tension of the spring will be increased or diminished by means of the collar 24, which through its engagement with the eccentric will be moved back and forth on the sleeve.

Having thus fully described our invention,

what we claim as new, and desire to secure by Letters Patent, is-

In a speed-regulating apparatus, the combination with the main shaft journaled thereon, a' pulley and a disk mounted to turn in unison on said shaft and adapted to receive ower from a primary source, another pu ley and another dis movably but non-rotatably mounted with respect to said shaft on the same and adapted to transmit power to the machine to be driven, a spring-actuated sleeve mounted on the shaft to turn therewith but so as to move longitudinally thereon and connected at one of its ends to the last-named pulley, weighted governor-arms pivotally connected at one of their ends to said sleeve, links uniting said arms between their ends to the said shaft, a grooved collar mountedon the sleeve in engagement with the actuating-spring' thereof, an eccentric journaled on the main frame in engagement with said collar, and means to turn the eccentric and to secure it against movement, substantially as described.

In witness whereof we have hereunto signed and sealed this specification this 18th day of January, A. D. 1906. Q
